Are you sure that you have a non-hacked dump? I've never seen an official release with a PAL region code and E as the fourth character in the game ID, and that would be the only possibility if Dolphin is showing you what's in that screenshot.

I cannot verify 100%, my country tends to be the most pirateable country in the world. Seemed weird that this very specific title had a region. Anyone else with this game can confirm my game has been modified ?
